Abstract: 564,401. Bending or straightening wire &c. BRITISH INSULATED CABLES, Ltd., LONDON PASSENGER TRANSPORT BOARD, HOLLAND, J., and POWELL, H. J. May 5, 1943, No. 7079. [Class 83 (iv)] In a manually-operated tool for straightening or bending wire, tubes, bars, &c. particularly for straightening kinks in overhead traction wire, of the kind having two pressure members which move over the work with a rolling action, the members are mounted between pairs of side plates forming two frames, one side plate of one pair being hinged to the corresponding side plate of the other pair while the other side plates are releasably connected together so that the two parts of the tool can be swung apart on the hinges so as to be readily placed over the work and then closed down on it and refixed in operative position. The top frame consists of side plates 3, 4, connected together by distance pieces 5 and nuts 6 and provided with a cover 36, and the lower frame consists of side plates 37, 38 connected together by distance pieces and nuts 43. The top frame mounts two grooved rollers 9 to which are attached gear wheels 11 which may be driven by a pinion 14 on a shaft 15 rotatable by a handle 30 so as to traverse the tool along the work. The shaft 15 is fixed in operative position by a semi-circularly-recessed spring- controlled pivoted locking member 25 which engages a groove in the shaft. The shaft may be moved axially so as to bring the pinion out of gear so that the tool :may be moved rapidly along a straight portion of the wire to be treated without the necessity for operating the handle, the shaft being held in position by engagement of the member 25 with the collar 24 on the shaft. The member 25 has a handle 35 to facilitate operation. The bottom frame which carries three rollers 41 in staggered position relatively to the rollers 9 has its side plate 38 mounted on hinge bolts 48 which are attached to a pair of hinges 47 on the plate 4 so that the top frame may be swung on the hinges 47. The side plate 37 is provided with a pair of lugs 54 between which may be received a swing bolt 53 hinged at 52 to the side plate 3 and provided with a nut 55 so as to release or clamp the top frame as required. The lower frame is adjustable to suit the size of wire or degree of deformation thereof by the nut 55 and by nuts 50 carried by the hinge bolts 48. The side plate 38 has a lug 57 for receiving a handle 56 for steadying the tool during operation. When used for bending, the two end rollers 41 are removed.

Title: Method and system for determining reflectivity of the ocean bottom
Inventor: MACDONALD FRANK HARLAN
IPC: G01S15/18
Filed: 1969-02-10
Abstract: 1,254,728. Determining reflectivity of the ocean bottom. TEXAS INSTRUMENTS Inc. 10 Feb., 1969 [24 May, 1968], No. 7112/69. Heading H4D. [Also in Division G4] A substantially real time indication of the acoustic reflectivity of the ocean bottom is provided by generating electrical signals respectively representing the energy of a transmitted sonar signal and of its echo from the bottom, the water absorption losses of the sonar signal, and the losses due to spreading of the sonar beam, and by processing these electrical signals in an analogue computer. The computer in practice provides a bottom loss indication Bl/10 (expressed in dB) given by 2 log 10 (Vs/Vr) +T/10 + G/10 - 2 log 10  2D - αD/5 where V s  is the peak amplitude of the transmission signal applied to the sonar transducer, V r  is the peak amplitude of the resulting bottom echo signal generated by the receiving circuitry, T is the transducer transmitting/receiving efficiency, G is the receiving circuitry gain, D is the ocean depth and α is the acoustic absorption coefficient of the water. The V s  and V r  signals are derived from peak-detecting amplifiers, the T and G signals are derived using reference voltages (the T signal is adjusted according to the particular sonar apparatus used), and the D signal is derived by converting to analogue form the output of a digital counter/timer which is started by the sonar transmission pulse and stopped on receipt of the bottom echo. This D signal is also applied to a depth readout unit. Logic circuitry may be used to ensure that V s  is measured at the expected transmission time and that V r  is measured only if the bottom echo is received from within a range "window" which in each transmit-receive cycle is automatically positioned to embrace the expected position of the ocean bottom as predicted by the bottom echo time measurement of the preceding cycle; false reflectivity computations due to spurious echoes from plankton &c. are thus avoided. Details of the analogue computer (see Division G4) and of the logic circuitry are given. A lamp may be energized if the automatic positioning of the window fails.

Filed: 1957-03-07
Abstract: 830,234. Charging refuse vehicles. SCHMIDT, K. H. March 7, 1957, No. 7539/57. Class 78 (4). While a member 5 charging refuse from a charging chamber 4 into the main chamber 1 of a refuse vehicle is in its forward position 5<SP>1</SP> refuse may still be tipped from bins into an auxiliary charging chamber 7 from which it is transferred to the charging chamber 4 after the member 5 has been retracted. The auxiliary chamber 7 may be mounted at the side of the charging chamber 4 and the refuse transferred by movement of a wall of the auxiliary chamber or, as illustrated, the auxiliary chamber 7 may be mounted beneath the charging chamber 4 and the refuse transferred by movement of the  floor 8. The floor 8 is shown as guided by guides 11, 12 and is moved by rams 9 pivoted to the floor 8 about an axis 15 such that the plate 8 first pivots about one end to the position 8<SP>11</SP> and subsequently about the other end to the position 8<SP>1</SP>. The member 5 comprises a flat plate driven by a pair of rams 6 mounted outside the vehicle and having at its lower end a flap 5b which can turn about a hinge 16, preferably against the action of a spring, if it encounters refuse at the top of the auxiliary chamber 7 as the flap 5 is retracted. Material which lodges behind the panel 5 is broken up by a flap 21 swinging about its upper end 22 and falls down an incline 19 into the chamber 7. A shield 20 on the floor 8 prevents material from the incline 19 passing beneath the floor 8. The charging chamber 4 may be shaped so that the refuse is compressed as it is pushed into the main chamber 1 or the compression may be effected by suitable control of a gate preventing reflux of material from the chamber 1. The flaps 5 and 21 and the floor 8 may be controlled so that their motions occur in the proper order and they may all be driven from the drive by which dustbins are tipped into the chamber 4. In an alternative embodiment the refuse is moved along the charging chamber 4 by a swinging flap pivoted at its upper end and the floor 8, which is arcuate in shape to conform to the path of the lower end of the swinging flap, rises bodily instead of pivoting as shown.

Filed: 1967-02-17
Abstract: 1,195,028. Safety harness. TELEFLEX PRODUCTS Ltd. 12 Feb., 1968 [17 Feb., 1967], No. 7794/67. Heading A3V. An inertia reel for a safety harness (Fig. 1) has co-axially mounted rotary members 16, 18 that normally rotate together through balls 31, and interengaging dogs 32 that sustain the torque reaction due to locking but have sufficient free movement to allow the relative rotation of the members necessary to occasion locking. A sudden pull on the safety belt causes the member 16 to rotate relative to the member 18 so that the balls 31, which are mounted between the members in mutually opposed tapered sockets, produce axial movement of the inertia member 18 thereby causing the engagement of teeth 28 on the member 18 and a brake ring 27. A pendulum 24 responsive directly to vehicle acceleration having a surface 26 of high friction material also serves to lock the reel by the engagement of this face with the periphery of the inertia member 18. The spring torque is adjustable by holding the end of reel 11 by means of a socket normally covered by the cap 34 and adjusting the spring cover 22, thus altering the tension of spring 21 which is attached thereto by one end, the other being secured to the reel 11 by a spigot 20.
